@kevdotward: Just to be clear, the update with multi-level grids is not ready and has not been sent to Epic. The one I have sent them is the one with an overhauled edge array, touch support, improved AI ++. It will still be some time before multi-level grids are ready, though it will take much less time than my previous update, as most of the features are pretty far along already.
**@: **I see. I though you meant tiles in sight range for attacking with ranged units. The ones in the screenshot are tiles in move range, right? You want to display what tiles can be reached when the teleporter is taken into account? For tiles in move range you will not be able to go from one height to another one if the two levels are separated by impassable edges and you are simply teleporting them from one to the other. Problems like this one is one of the reasons I changed the edge array. In the 1.5 update any tile can be set to be connected to any other tile on the grid, which makes adding teleportation easier (though you would still have to add the sudden location change of the moving unit yourself).
